Hey guys, my macbook first gen takes a really long time to boot up. the grey screen is there for quite a while, and then a blue screen for even longer time before it actually gets to the login screen. I'm worried if there's a problem, specifically with the hard drive as I had to get that replaced about 8 months ago. I'm concerned that the macbook eventually won't boot up at all. I leave my macbook on all the time, it doesn't go to sleep mode either just the screen goes off. Am I doing damage to the hard drive or other components? cheers.
